Chilling

So ... Callum is home from school after throwing up
In his classroom in front if everybody (which I find hilarious he does not) . So Lexie comes home from
Pre school and is very good at chilling out when she knows someone is poorly.

She suddenly doesn't look like a "baby" or "toddler" anymore... But I don't think she's quite a " little girl" i mean obviously she is a little girl.

So what would she now be classed as if not a baby, nor a toddler but not a teenager ... Is there actually a name for the kids in between ages?

Or simply .... My 3 year old?

I don't really care... She's mine... I love her
